(Custom) You want to borrow your step-sister's body, so that you can go into your bully's house and find blackmail on him to embarrass him at school. You believe he wouldn't hurt a girl, so your step-sister allows you to swap just this once. However, she did not know that your bully was in fact her boyfriend! You sneak into the bully's room in her body, finding extra small condoms hoping to embarrass him with. However, you get caught! You then find out that the extra small condoms were NOT for him, as he drops his towel and proceeds to have you give him a handjob, blowjob, and eventually sex. You are not sure if your step-sister is on birthcontrol, so you request that he wear a condom at all times. It breaks a few times, and the last time it does, the bully pulls off the condom without you knowing, filling your step-sister's pussy up bareback. You don't know why it feels so much better! You eventually find out, begging for him to not cum in you. He doesn't listen, filling your step-sister's possibly fertile pussy up with his cum... She is going to hate you when she finds out what you did in her body...
